Key Biological Pathway Linked to PTSD

Dr. Ressler's paper in Nature was covered by more than 25 media sources. He and his collaborators discovered a key biological pathway, PACAP (pituitary adenylate cyclase-activating polypeptide), linked to PTSD. The team, with ACTSI support, studied a group of 64 highly traumatized civilians (not veterans) treated at Grady Memorial Hospital.
